40 students
12-A
18-B
40-12=28
28-18=10
10/40 did not vote.
25% did not vote
10 is one fourth of 40
fourth of 100% is 25%

find the length of the side of square with an area of 121 in2. A.484 in, B.30.25 in, C.11 in, D.6.5 in

marishachu [46]

For a square, the area is the square of the side length (length x width = area, but in a square length = width). That means the side length is the square root of the area.

In this case the side length is the square root of 121, which is 11. Answer is C.

Answer:

$\binom{6}{2} = a_{0}=15$

Step-by-step explanation:

$\binom{6}{2} = a_{0}$

$\binom{n}{r} =\frac{n!}{r!\times(n-r)!}$

It is representing a combination form where, n is number of items we have and r is the number of items we choose from n

Here, n = 6 , r = 2

$\binom{6}{2} =\frac{6!}{2!\times(6-2)!}$

= $=\frac{6!}{2!\times(4)!}$

$n!=n\times(n-1)\times(n-2)\times(n-3).....\times3\times2\times1$

$=\frac{6\times5\times4!}{2\times(4)!}$

$=\frac{6\times5}{2}$

$={3\times5}$

$={15}=a_0$

Thus, $\binom{6}{2} = a_{0}=15$

1. What is (f⋅g)(x)?

nekit [7.7K]

Answer:

(f⋅g)(x) $= x^7 + 9x^4 - 9x^3 -81$

$(f - g)(x) = x^3 - 6x^2 + 18x + 6x - 10$

Step-by-step explanation:

For the first part of the question we have two functions

$f(x) = x^4 -9$

$g(x) = x^3 + 9$

If the expression refers to the multiplication of f and g, then:

(f⋅g)(x) $= f (x)g(x)$

So we multiply the function f(x) with the function g(x)

(f⋅g)(x) $= (x^4 - 9)(x^3 + 9)$

(f⋅g)(x) $= x^7 + 9x^4 - 9x^3 -81$

For the second part we have the functions:

$f(x) = x^3 -2x^2 + 12x - 6\\\\g(x) = 4x^2 - 6x + 4$

We wish to find (f - g) (x). We know that

$(f - g)(x) = f(x) - g(x)\\\\(f - g)(x) = x^3 - 2x^2 + 12x - 6 - [4x^2 - 6x + 4]\\\\(f - g)(x) = x^3 - 2x^2 + 12x - 6 -4x^2 + 6x - 4$

$(f - g)(x) = x^3 - 6x^2 + 18x + 6x - 10$
